Khaho ea Mochini oa Diesel Exhaust Gas Turbocharger

Lijenereithara tsa diesel li na le li-turbocharger tsa enjene ho matlafatsa matla a likarolo tsa tsona.E entsoe ka likarolo tse kholo tse kang turbine casing, casing e bohareng, compressor casing, 'mele oa rotor le li-bearings tse phaphametseng.Khase ea turbine e hokahane le phala ea ho tima enjene.Ho kenella ha "compressor casing" ho hokahane le tsela ea moea ea sefefo sa moea, ha phallo e lebisa ho silindara ea enjene.The diffuser ea compressor e thehoa ke lekhalo pakeng tsa compressor casing le bohareng casing.

'Mele oa rotor o na le rotor shaft, compressor impeller le turbine, tse nang le welded holim'a rotor shaft.The compressor impeller ke aluminium-gold casting 'me e tsitsitsoe holim'a rotor shaft e nang le nate.'Mele oa rotor o lokela ho hlahlojoa bakeng sa ho leka-lekana ho tsitsitseng le ho leka-lekana ho matla pele o kenngoa ho supercharger,' me tekanyo ea eona e sa leka-lekaneng e lumelloa ho ba ka har'a mefuta e itseng.
